Abstract: Proposed is a piston (1) for an internal combustion engine having a closed annular duct (4) which is arranged close to the piston head (5) and radially at the outside, which annular duct (4) has, at the piston head side, an annular opening (21) which, in section, has the shape of a trapezium with limbs which taper conically in the direction away from the piston head, and which is closed off by an annular closure element (3) which, in section, has the same trapezium shape as the opening (21), with the closure element (3) being fastened in the opening (21) by means of friction welding.
Abstract: A method subsequently reinforces injection-molded transporters such as plastic pallets, which have support feet disposed on their underside, at least at the corners, and a groove for inserting a reinforcement profile between two support feet that stand diagonally opposite one another, and the two ends of the groove are formed by pockets shaped to correspond to the profile cross-section, disposed in the region of the support foot assigned to the groove end, in each instance. After completion of the pallet, the distance between the two pockets is increased via elastic deformation of the pallet. Afterwards, the reinforcement profile is laid into the groove, and one end of the profile is laid into one of the pockets. Thereafter, the deformation is canceled out and the pallet returns to the relaxed original state, and in this connection the other end of the reinforcement profile also dips into the corresponding pocket.
Abstract: The invention relates to a device for loading a patient connector for peritoneal dialysis with a closure plug. To permit an arbitrary number of disconnection/connection procedures with patient connectors that insert a sterile closure plug into the patient's abdominal connector during disconnection, a device for loading a patient connector for peritoneal dialysis with a closure plug is suggested, said device consisting of a housing containing a closure plug and of means for transferring the closure plug out of the device and into a patient connector. This permits loading, under sterile conditions, of a patient connector whose closure plug has already been used with a new closure plug. By loading a new closure plug, the push-button with which the closure plug is inserted is returned to its starting position, so that the patient connector is again available for a connection/disconnection procedure.

Abstract: A sales and presentation area has an essentially annular region rotatably mounted in the horizontal direction, divided into ring segments able to be moved individually in the vertical direction, and set into horizontal rotational movement via drives during use of the ring segments by customers. A changing section along the path of the moving annular region is kept inaccessible for customers from the exterior of the annular region. A lifting and lowering device is provided beneath the changing section. The ring segments slide over the lifting and lowering device in the course of the rotational movement of the annular region and rest on the lifting and lowering device during a standstill of the annular region for moving the ring segments in the vertical direction. The ring segments may be pushed in the radial direction into rooms below the sales and presentation area.
Abstract: A multi-functional board-type gliding device, which has two end portions spaced at a distance apart from another in the direction of a longitudinal axis and is designed to be split in its longitudinal extension to form gliding part-devices . Several first and second coupling mechanisms are disposed in the direction of longitudinal extension in order to provide a mutual connection between the two gliding part-devices. The two mutually coupled gliding part-devices constitute a first operating mode and in the position separated from one another constitute a second operating mode. In the first operating mode in the coupled position, the two gliding part-devices form a first end portion which defines a first direction of use. In the second operating mode in the position separated from one another, the or the other end portions define a second direction of use opposite the first direction of use.

In order to determine the position of distance between the end of the welding wire (13) and the workpiece (16), which is to be processed, in a manner which is as accurate as possible, at least one mechanical adjustment process (41) is carried out during the welding process, enabling the position of said welding wire (13) being used as a sensor.
Abstract: A gearless speed reducer or increaser consists of an input shaft, an output shaft, and a motor connected to the input shaft. There is an external race connected to one of the shafts, and an internal race attached to the other shaft. Two ball bearings are disposed between the races. After the ball bearings have been inserted, the shafts are tilted relative to each other so that the balls become fixed in pockets created between the races and cannot slide within the races. Rotating one of the shafts thus rotates the other shaft, since the balls do not slip but only rotate between the races. The system acts as a speed reducer or increaser due to the different diameters of the inner and outer races. The system can be uncoupled by pivoting the shafts back into alignment so that the balls can slide freely within the races.
Abstract: The invention relates to a bearing element (1) with a metallic support body (2), a bearing metal layer (3) arranged over the top and a polymer layer (4) arranged on the top of the latter, whereby the polymer layer (4) consists of a polyimide resin, molybdenum sulphide (MoS2) and graphite. The proportion of the polyimide resin in the polymer layer (4) is selected from a range with a lower limit of 60% and an upper limit of 80%, the proportion of MoS2 is selected from a range with a lower limit of 15% and an upper limit of 25% and the proportion of graphite is selected from a range with a lower limit of 5% and an upper limit of 15%.
Abstract: In a space shuttle with a device for docking to a satellite, especially a communication or navigation satellite, at least two spreading elements in the form of lever spreaders are pivotally disposed at a retaining part of the docking device, which is concentric to a linkage. The lever spreaders have their proximal ends—relative to the space shuttle—provided with inward projections projecting inward towards the linkage, which inward projections engage in a recess formed in the linkage when the lever spreaders, spread apart to a defined opening angle by the cone of the linkage. When the linkage is retracted further, a pressure spring is compressed. At the same time, the lever spreader caught in the recess are retracted so far that the ends of the lever spreaders, spread apart in a defined manner, positively abut the inner wall of the nozzle neck.

Abstract: An elastic shaft coupling has a drive-side interface and an output-side mechanical interface. Both interfaces are intended in each case for connecting the shaft coupling to an adjacent machine element. The shaft coupling has at least two elastic rubber elements which are connected behind one another between the drive-side and the output-side interfaces and the axial material thickness of which increases in each case at a growing radial spacing from the center axis of the shaft coupling. To reduce the amount of rubber of the shaft coupling with retention of its elastic properties, the respective rubber elements are of non-uniform configuration with regard to their torsional rigidity and to be precise are so non-uniform that the torsional rigidity of one of the two rubber elements is always at least one and a half times as great as the torsional rigidity of the other rubber element.
